There is a similar quote that I like better: "A great man shows his greatness by the way he treats lesser men."

Unfortunately there are many people who are so self-absorbed that they have no time for other people unless they can derive some benefit from dealing with them. A man who tries to help someone who needs help with no thought of anything other than just trying to help someone who needs help is a far better man.

The same thought is expressed in the New Testament with the parable of the Good Samaritan.

It means there are two kinds of men. ONE sees a man struggling to change his flat tire, and walks by without a second thought. Another man sees the same thing, and offers to help. The one offering to help, expecting no payment or other reward, is a better man.
